There is nothing wrong with acronyms and difficult language, until there’s someone in the room who can’t relate.
Suggestions if you struggle with this:
- Record yourself speaking during a similar presentation or meeting and check the language
- Read the last few emails you sent to someone external to your immediate organization
- Run the 8 year-old test
Make your language easy to understand. If you do, the people you want to reach will know exactly what you are trying to say.
